FIG. 1 is a perspective view of an implantable, self-expanding stentshowing our new design;

FIG. 2 is an enlarged front-end elevational view thereof;

FIG. 3 is an enlarged side elevational view thereof;

FIG. 4 is a perspective view of a second embodiment of the implantableself-expanding stent;

FIG. 5 is an enlarged front-end elevational view thereof;

FIG. 6 is an enlarged elevational side view thereof; and,

FIG. 7 is a fragmentary side elevational view of a third embodiment ofthe implantable self-expanding stent.

The ornamental design of applicants' implantable self-expanding stent isdirected to a plurality of flexibly interconnected cells extendingaround the circumference of the tubular-shaped stent and forming a rowtransverse to the longitudinal axis of the stent. The longer sides of anexpanded cell are circumferentially oriented and transverse to thelongitudinal axis; whereas the shorter flexibly interconnected sides ofeach cell are substantially aligned with the longitudinal axis. Cells inadjacent rows are circumferentially offset from each other. The flexibleinterconnections between cells in a given row are wound in one directionor an other with the flexible interconnection of the cells in anadjacent row being wound in the opposite direction. Loops are positionedat the front end of the interconnected cell design. In another aspect ofthe design, windings of adjacent, front end loops are wound in oppositedirections.
